The error is that 15 was subtracted on the left side when it should’ve been added.
Corrected equation:
27 = n-15
Add 15 to both sides
42 = n
Answer:
12
Step-by-step explanation:
Arranging in ascending order -> 9, 10, 12, 12, 13, 15, 16
n = 7
Median = value of ((n + 1) / 2) th term
= value of (7+1) / 2 th term
= value of 4 th term
= 12
Hope it helps :)
We get the value of h and k as 9 and -8
The quadratic function g(x) = a(x - h)^2 + k, if a is not equal to 0,which means that equation has a quadratic value then it is said to be in standard quadratic form.
If a is positive, then the graph opens upwards,
If a is negative, then it opens downwards.
The line of symmetry of the quadratic equation is the vertical line x = h, and the co-ordinate of the point of vertex is (h,k).
We are given the co-ordinate of the vertex point in the question and hence all that is required is to equate it.
Therefore, the values of h and k are 9 and -8 in the given equation in vertex form
